CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 276,025, dated April 17, 1883.

Application tiled October 17, 1882. (N o model.)

To all whom fit may concern:

Beit known that we, JOHN GoE'r'rEL and E. T. SLAYTON, citizens of the United States, and residents of St. Paul, in thecounty of' Ramsey and State of Minnesota, have invented a new and valuable Improvement in Oar-Couplings; and, we do hereby declare that the following` is a full, clear, and exact description of the ence being had to the annexed drawings, making a part of this specication, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a.top View of our car-coupler. Fig. 2 is a side view, partly in section. Fig. 3 is a front view. Fig. 4L is a perspective view of the coupling-hook, and Fig. 5 is a detail View. j

This invention has relation to car-couplings 5 and it consists in the novel construction and arrangement of parts, as 'will be hereinafter fully described, and pointed out in the claims appended.

In the accompanying drawings, the letter a designates the holder or attachment plate, whereby the coupling is connected to the under portion of the car-frame. This plate is formed with a central longitudinal chamber, the side walls of which are re-enforced atb, the re-enforced portions being connected by a transverse partition, c, having a central perforation, through which passes the tie-rod el, to the front end of which the draw-head E is pivoted. In front and in rear of the partition c on the tie-rod are the springs c, which consist usually of rubber cores gwithin binding spiral springs h. On the rear lend of the tie-rod is a follower-bearing, It, and on the front end of said rod, in rear of the end of the draw-head E, is asimilarfollower bearing or plate, k. The ends l of the re-enforcements b of the .side walls of the attachment plate or holder form abutments, against which the follower-plates work .when the springs are pressed home.

The draw-head E consists of a stem or shank, m, and head N. The rear end of the shank is seated in the front end of the holder and is pivoted to the tie-rod. Guides p at the front end of the holder serve to keep the draw-head in working position and yet allow thedraw-head some lateral upward and downward and rotary play, so that it can readily accommodate itself kthat of the car to which it is coupled.

tothe position of the car with reference to The head N of the draw-head is formed with a rear plate, e', from which extends forward a lateral 55 cap or box bearingconsisting of the side wall,

r, the forward curved guard-flange, f,laterally opposite the side wall,r, the upper wall or bearing, s, and the lower wall or bearing, s'. Io the front inner corners of the bearings s and 6o s is pivoted, by the king-bolt q, the hook-jaw A, said king-bolt passing through vertical perforations in said bearings, and through a vertical perforation in the hook-jaw the curved ange of the head f extends forward and 6 5 serves to secure the hook-jaws when engaged, and to prevent them from spreading apart when making short curves or passing over inequalitie-sinthetrack. Eachhook-jawismade sufficiently deep at its front end to insure en- 7o gagement with the hook -jaw of the opposite coupler. It consists of a hook-head, a', and a rear wing or tail portion, b', which is about as long as the head af, the perforation for the king-bolt being arranged at or nearly at the junction of the head and tail portion. The front c of the head is convex from side to side, and is formed with transverse slots d and vertical perforations c', communicating with said slots, and serving for the passage of a coupling- 8o pin, g', designed to be used when a car having this draw-head is to be connected to a car having the ordinary link-coupling. To the tail of the hook-jaw is pivoted a laterally-extending arm, t, which projects through an aperture, o, in the side wall, a, of the head N. To the outer end of the arm tis pivoted a second joint, fw,

of said army-which is formed with a stop-bear ing, z, whichjengages the main arm ton its upper edge, both when the second joint is 9a iiexed on the main arm and when it is in line therewith. The inner end of the second or lockingjointto is formed with a catch, h', which, when the outer end of said joint is pressed down, rises out of line with the main arm t and engages the bearing-edge of the aperture v.- When, however, the second joint w is raised by means of suitable connecting-rods extending upward or laterally, so as to be within easy reach of the brakeman, it is brought 10e in line with the main arm, and will then slide freely inward throu gh the aperture o, allowing` 'other automatically, and are automatically secured in the engaged position by the gravitation of the outer ends of the locking-joints w, and the consequent engagement of the catches h with their bearings on the draw-heads.

The draw-head for a freight-car is usually made with a shoulder, z', back of the head N and facing to the rear, while the draw head for a passengercar has no shoulder, as it is designed to work freely under the car, where the dead wood may be fastened; but either form may be employed for cars of all kinds.

A vertically-swinging draw-head has been combined with afulerumed side leverattaehed thereto and locked by a weighted pawl. Automatic couplings are not broadly new in this connection, and laterally-swinging hooks, levers, and springs have been combined in carcouplings. We do not therefore claim either of the constructions broadly herein.

Having` described this invention,what we claim, and desire to secure by Letters Patent, 1s-

1. A pivoted hook-jaw, A, connected to lateral bearings s sof the head N of the draw-bar E, a lock-catch, h', and the pivoted arm .w of l the hook-j aw carrying said lock-catch, substantially as specified.

2. In an automatic car-coupling, a lateral hook-jaw, A, pivoted to bearings in the head of the draw-bar E, and having a rear wing, t, carrying a pivoted arm, w, provided with an automatic lock-catch, h', substantially as specitied.

3. The draw-head formed with laterally-arranged bearings, s s 'for the pivoted hook-jaw A, and laterally opposite the same a forward curved flange-guard,f,substantially as specitied.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
